Kuhn, W. 198 55. 11%3 RacineAve, Rte. 3, Muslregou, Wis. Filed July 24, 1963, Ser. No. 297,288 1Claim. (Ci. 49-397) The present invention relates to top hung pivotedwindow sash of the type customarily embodying a plurality of lighttransmitting panes. Such sash is customarily used in industrialestablishments and is employed for both ventilating and lighttransmitting purposes. Hence it is pivoted along the top edge thereof soas to swing outwardly when opened, for passage of (both light and air.When the sash is closed it provides a Weather seal with the adjacentbuilding structure.

The present pivoted sash may be initially installed upon a new buildingor may be employed to replace existing conventional fixed or movablesash. Accordingly, the sash of the invention provides its own weatherseal with the building, whether such seals be with the original windowsill members or additional sill members in stalled during a renovation.Therefore, the invention also embodies suitable end sealing means aswell as 1ongitudinal sealing means.

Aluminum has been currently used as sash material due to its lightnessand corrosion resistance. Due to the wide variety of window sizeopenings encountered in industrial buildings, the sash is usually custommade even though certain stock sizes may also be available or embodiedtherein. The present invention thus embodies construction whichfacilities custom construction from long stock lengths of the sashmembers; such sash members may be of aluminum, rigid vinyl or othersuitable materials.

Industry now customarily employs corrugated plastic sheets as windowsdue to its resistance to breakage. The invention, therefore,contemplates a readily adjustable sash for receiving a plurality ofdifferent widths of such plastic sheets during initial construction.

One object of the present invention is to provide a top hung pivotingsash construction which readily lends itself to custom construction tomeet the users needs.

Another object of the invention is to provide a sash of the characterdescribed which readily seals itself against weather and dirt.

A further object of the invention is to provide a simple economic designof sash which is strong and is assembled with a minimum of labor.

These and other objects of the invention will be made apparent from thefollowing description and the drawing forming a part thereof, wherein:

FIG. 1 shows in front elevation a portion of a building with a sash ofstandard length comprised of three panels;

FIG. 2 shows an enlarged typical vertical section taken on lines II-IIof FIG. 1;

FIG. 3 shows an enlarged typical longitudinal section taken on linesIII-III of FIG. 1;

FIG. 3A shows an enlarged typical longitudinal section taken on FIG. 1illustrating the manner of splicing two standard frames.

FIG. 4 shows an enlarged typical vertical section taken on lines IVIV ofFIG. 1, illustrating a typical crosssection through the panel splicebars; and

FIG. 5 shows an enlarged typical vertical end view of the sash taken onlines V-V of FIGS. 1 and 3.

Referring now in detail to the drawings, particularly FIGS. 1 and 2, thesash of the invention may be disposed vertically in substantiallyparallel relation to the building vertical wall within which the sash ismounted, or the Patented August 16, 1966 sash may be sloped outwardly aswhen the sash is mounted in a monitor or saw toothed roof structure. Forpurposes of illustration the sash of FIG. 1 will be considered as beingmounted in an elongated window opening in a vertical (wall of thebuilding. The metal upper sill 1 of the window opening is disposed insubstantially the vertical plane of the building wall 2 and the bottomsill 3 of the window opening is recessed inwardly of the vertical planeof the Wall 2. At each vertical side Wall of the window opening is avertically disposed substantially Z shaped flashing member having oneinturned leg 4 secured to the building wall, a web member 5 disposed ina direction transversely of the window opening and an outtunned leg 6.

Secured to the inner face of the upper sill 1 and extending transverselyof the window opening is the sash hanger member indicated generally as 7and which may be longer than the sash top member. Member 7 is preferablyan aluminum extrusion comprised of a plate-like body portion 8 havingsuitably spaced openings 9 therein receiving suitable fasteners 10attaching it to the sill 1. At the upper end of the body portion 8 is athickened portion 11 having a substantially circular passageway 12therethrough with a slotted opening 13 in the periphery thereof. Mountedin said pasageway 12 and extending through said opening 13 is dirt guard14 overlapping member 17. At the bottom of body portion 8 is an arcuateoutwardly projecting portion 15 having an enlarged inturned portion 16disposed in spaced relation to body portion 8 and arcuate portion 15providing a pivotal support for the movable sash frame top member '17 ashereinafter discussed. The herein described member 7 is illustrated inFIGS. 2 and 5. An alternate form of member 7 is shown in FIG. 4, whereinmember 7A at the upper end of plate portion 8a is flat and has on theinner surface thereof a recess A receiving the flange 14b to retain themember 14a in position. Member 14a and member 14 are of any suitablematerial such as vinyl plastic or metal and extend substantially thelength of members 7 and 7a.

The movable sash frame is comprised of top and bottom members indicatedgenerally as 17 and 18, connected by intermediate members and endmembers indicated generally as 19 and 20 respectively. Top member 17preferably of extruded aluminum having a. rear wall 21 terminating atthe lower end thereof in a flange Z2 and terminating at its upper end ina forwardly extending arcuate portion 23. Intermediate its ends wall 21has a fonwardly extending portion 24 terminating in a depending wall 25having an inturned bottom flange 26 spaced from flange 22 of Wall 21.The portion 24 with walls 21, 25 and their opposing flanges provide anenlarged recess to receive the ends of the plastic panels and theirclosure member. Walls 21 and 25 have on their inner faces opposingprojections 27 and 27a.

The sash bottom member 18 is preferably an aluminum extrusion ofsubstantially angle shape having a front wall 28 and rearwardlyextending top wall 29. Extending longitudinally of the under surface ofwall 29 are passageways 30 for engagement by screw-threaded fasteningmembers as hereinafter discussed. Upon the front face of wall 28 is alongitudinally extending closure member supporting ledge 31 and asimilarly extending recess 32 for engagement by screw-threaded panelfastening members, as hereinafter discussed. Upon the inner face of wall28 adjacent the lower end thereof, is a suitably shaped longitudinallyextending recess 33 for reception of a sealing member, such as 34,providing a weather seal with the adjacent face of building window lowersill 3.

Extending between the upper sash member 17 and lower sash member 18inoverlapping relation therewith are a plurality of spaced suitablycorrugated plastic panel members 35. The adjacent spaced vertical edgesof such panels 35 are secured in place by struts or mullions indicatedgenerally at 19, extending between the sash members 17 and 18. Eachstrut 19 is comprised of an inner member 36 and an outer member 37.Inner member 36 is preferably an aluminum extrusion comprised of alongitudinally extending transversely disposed Web portion 38 having onits rear face a centrally disposed rearwardly extending portion 39.Extending forwardly of web 38 and preferably equally spaced about thelongitudinal center line thereof are two longitudinally extendingportions 40 spaced at 49a to be engaged by a screw-threaded memberentered between them. Extending laterally outward from each portion 40is an arcuate portion 41 conforming substantially to the contour of theadjacent edge portions of a plastic panel to be engaged therewith. Each-arcuate portion 41 is preferably provided with longitudinally extendingserrations 42 to grip the plastic panel engaged therewith. As shown inFIG. 4 of the drawing, member 36 has the portions 40 removed adjacentthe upper end thereof so that the web 38 may overlappingly engage theinner face 21 of top sash member 17 and secured thereto by suitablemeans such as screws 59. Member 36 has the web 38 removed from a portionof the lower end thereof so that portions 40 may overlap and abut thefront face 28 of the bottom sash member 18 with portion 38 substantiallyabutting portion 29 and secured thereto by screw fastener 60. The outerstrut member 37, as best shown in FIGS. 3 and 4, is comprised of a flatlongitudinally extending central portion 43 having laterally extendingarcuate portions 44 at opposite sides thereof. The inner faces ofar-cuate portions 44 have longitudinally extending serrations forgripping the plastic panel engaged thereby. Suitable apertures 45 spacedlongitudinally of member 37 receive screw-threaded members 46 whichengage the inner faces of portions 40 and member 36, cutting threadstherein, to clamp the two members 36, 37 together with the edge portionsof the plastic members disposed between them. As best shown in FIG. 4,inner strut member 36 at its upper end overlaps wall 21 of sash member17 and is attached thereto by suitable fasteners 59, and the base ofstrut member 36 is disposed adjacent Wall 29 of bottom sash member 18. Asuitable fastening member 60 connects said wall 29 with portion 39 ofthe strut 36.

Defining the vertical end edges of the sash, as best shown in FIGS. 3and 5, are oppositely disposed angle members 20 and 20a extendingbetween and connected to the ends of the upper and lower sash members17, 18. As best shown in FIG. 3, member 20a is opposite hand to 20. Theupper end of legs 48 and 48a of the members 20, 20a are inwardly offsetto engage the face 21 of upper sash member 17. The lower ends of legs49, 49a overlap the end face of lower sash member 18.

As best shown in FIG. 3A the sash may be custom made to any desiredlength. Additionally certain lengths and widths of sash have been moreor less standardized in the industry and several lengths of the members17, 18 of such standard sizes may be assembled end to end to provide anydesired length of sash to be handled as a unit, in opening and closingfor ventilation. In such instances end members 20, 20a may be deleted atthe intermediate joints and the adjacent ends of lower sash member 18may be connected by a suitable splice member 50. Member 50 preferably ofangle shape having one leg 51 overlying bottom sash portion 29' and ashorter leg 52 embracing the inner end of portion 29. For splicing thetop sash member 17, the splice plate 50 may be omitted since web 38 ofthe member 36 secured thereto serves the same purpose.

The corrugated plastic panels 35 extending between the top and bottomsash members 17 and 18 are sealed therewith by any suitable form ofconventional closure strip conforming to panel corrugations. As shown inFIG. 4,

the portions 22, 26 of the top sash member 17 freely receive the overallthickness of the corrugated panel 35 and suitable elastic sealing stripsS can be inserted between sash portions 21, 25. Similarly a conventionalsealing strip can be employed with the bottom of the plastic panel. Herethe sealing strip 53 at the base of the panel has partial support uponthe sash portion 31 and is secured to the bottom sash member 18 by thefasteners attaching the panel to portion 32 of the sash member.

The suspension of the sash, for pivotal movement is best shown in FIGS.2, 4 and 5. The arcuate portion 23 of sash member 17 substantiallyconforms to the contour of portion 16 of hanger member 7. As the sashswings to the left of the positions shown in FIGS. 2, 4 and 5, sashportion 23 rotates upon hanger portion 15 and the inner end of the sashportion moves upwardly relative to the arcuate portion 15 of the hangermember 7. Hence any accumulation of dirt, etc., upon the inner face ofsaid portion 15, cannot impede free movement of sash portion 23. Thedirt guard 14 overlapping sash portion 23 tends to prevent entrance ofdirt onto the inner face of hanger portion 15. Since the dirt guard 14or 14a is free to pivot upon its connection with member 7 or 7a, noappreciable resistance is offered thereby to free pivotal movement ofthe sash.

As best shown in FIG. 4, it is desirable to limit the inward movement ofthe sash as it moves from open to closed position. One suitableadjustable means for this purpose is the screw-threaded members 58mounted in portion 21 of sash member 17 and spaced longitudinallythereof. The head portion of the members 58 by suitable rotation may beadjustably spaced relative to hanger portion 15 to engage therewith andlimit closing movement of the sash.

Customarily such top hung sash, of the invention, is provided with meansfor holding the sash in any suitable spaced relation to the bottombuilding sill for ventillation purposes. Such means forms no part of thepresent invention and any conventional commercially available means maybe employed for this purpose.
